基于ENVI4.5的土地利用覆被信息监督分类对比研究——以海南省屯昌县为例
Comparative Study on Supervised Classification of Land Use and Cover Information Based on ENVI4.5
摘要
Abstract
Talcing Tunchang County of Hainan Province as test area, using present situation map of land use of 2005 and corrected SPOT image of 2008 as data, and using supervised classification in ENVI4.5 to extract cultivated land, garden and forest land information, and the extracted accuracy was compared and analyzed. The results showed that the extracted accuracy of parallel six surface method in cultivated land information was highest, and reached 85.60% , and the extracted accuracy of the minimum distance method in garden information reached 82% , the forest land information accuracy extracted by maximum likelihood classifier amounted to 80.38%. The phenomenon of "different objects same image" and "same object different images" are the main influencing factors of classification accuracy.关键词
